ADJUSTABLE SUPPORT FOR DOMESTIC HOT WATER BOILERS Filed Oct. 23. 1931 Patented Oct. 24, 1933 I UNITED STATES PATENT orrics ADJUSTABLE SUPPORT FOR- DOMESTIC HOT WATER BOILERS My invention relates to supports and more particularly to a support or stand for domestic hot water boilers.

Hitherto, it been proposed to make boiler stands as a single unit, that is, a stand having a unitary base and a flange or ring upon which the boiler rests. These devices, however, are not adjustable and for this reason, are open to the objection that a large number of such stands must of necessity be kept in stock to meet the demand for stands for boilers of different diameters.

It has also been proposed to use stands made in sections, the leg portions being formed of channel iron and havingarms attached thereto, the

arms overlapping at their free ends and adapted to be fastened so as to hold the sections together. In stands of this type,the bottom of leg memher is unprotected, and the sharp edges of the angle iron sink into the floor covering, frequently causing the covering to break in the vicinity of the point of 'contactwith the leg member. Due to the weight of the boiler and water contained therein, the'legs will form indentations in the floor itself, even though no floor covering is provided.

An object of my invention is to provide a boiler stand adapted to be adjusted to fit boilers of different diameters.

Another object of my invention is to provide a boiler stand having an improved foot arrangement associated with the legs of the Yet another object of my invention is to provide a boiler stand which is strong and sturdy in construction and adapted to be compactly folded 05 i for shipping purposes.

With these and other objects in view, which may be incident to my improvements, the invention consists in the parts and combinations to be hereinafter set forth and claimed, with the under- 40 l standing that the several necessary elements,

comprising my invention, may be varied in construction, proportions and arrangement, without departing from the spirit and scope of the appended claims.

In order to make my invention more clearly understood, I have shown in the accompanying drawing means for carrying the same into practical efiect, without limiting the improvements in their useful applications to the particular constructions, which for the purpose of explanation, have been made the subject of illustration.

In the drawing:

Figure 1 is a perspective viewof my improved boiler stand. I

Fig. 2 is a plan view of Figure 1.

Fig. 3 is a detail view of a modification; and

Fig. 4 is a view showing the stand in folded position.

Referring to the drawing and more particularly to Figure l, I have shown a boiler stand cornprising a plurality of leg members 1, having side or cross arms 2 attached to the leg members. One leg and its associated side arm constitutes a section of the stand and since the sections are alike and similar in construction, a description of one section'will sufdce, as the stand is made up of a plurality of such sections.

The legs are formed from angle iron pieces, having side members 3 and l. The side member 4 is cut away near its upper extremity, to form a notch 5 adapted to receive the edge or" a boiler. The lower end of member l is turned up to form a foot 6 upon which the leg rests. The side memher 3 or" the leg is provided with an aperture '7, the purpose of which will hereinafter be described in detail.

The cross or side arms 2 are radially disposed with respect to the leg members and consists of fiat pieces of strip metal. The pieces are slotted as at 8, each piece divided into two parts, in the form of tongue members 9 and 10.

In attaching the side arms to the legs, the portion 10 is passed through the aperture '7 and the end of portion 19 is turned over as at ll, thus securely holding the side arm in engagement with the leg. The tongue 9 which lies adjacent the portion 4 of the leg, renders additional support for the arm, whereby a rigid connection between the leg and side arm is obtained.

It will be appreciated that the arms may be welded to the leg portions, in which case the aperture 7 is eliminated. If the arrangement as shown is used, the member 9 may be spot-welded to the side of, portion 4 so that a perfectly rigid connection between the leg and the arm is assured. I

In prior art devices, using sections formed of leg and cross arm members, it has been customary to use cross arms of comparatively wide flat pieces of strip metal. The pieces are attached to the legs by means of rivets, the pieces being twisted to form 'ahorizontal portion provided with a slot or other openings whereby the sections are fastened together. In order to place the free end in a horizontal position, and at the same time provide sufficient area of contact with the leg, the arms as above noted, are made of wide strips of metal.

In my improved boiler stand, the arms are not twisted. They are formed of strips which are in by the sections are held together.

a horizontal plane throughout the entire length of each arm and are attached at right angles to the leg member. With my construction a much narrower strip can be used, thus afiecting considerable saving in material and other economies incident to the manufacture of the stand.

Referring to Figure 2, it will be seen that the ends of the arms 2, at the point of attachment to the legs, fit snugly against the inside of the angle member, the arm being perpendicular to the portion 3 of the leg. The free ends of the arms are provided with openings 12 adapted to receive a bolt 13 or other fastening means where- When the sections are assembled the ends overlap, with the openings 12 in register, the bolt 13 passing through the set of openings corresponding to a given diameter of a hot water boiler.

Referring to Figure 3, there is shown a modified form of connection between the leg and cross arm of my improved boiler stand. The side 3 of the angle piece is provided with an aperture 7' and side l has a cut out portion 14. Thearm 2 is cut away to form a projection 15 adapted to seat in the recess '14 of the side 4'. The cross arm is further provided with a tongue member adapted to pass through aperture 7, the tongue being turned over as at 16.

It will be seen that projection 15 fits snugly into the recess 14 and that the outside edge of the arm is flush with the surface of the angle piece. By means of the arrangement disclosed, a very tight and rigid connection is formed between the leg and arm members.

For packing and shipping purposes the stands are assembled and folded as shown in Figure l. It will be noted that the leg members are nested and the arms interfit so that a small and compact unit is obtained. The stands are readily assembled and can be installed with a minimum amount of labor. I

While I have shown and described the preferred embodiment of my invention, I wish it to be understood that I do not confine myself to the precise details of construction'herein set forth, by way of illustrations, as it is apparent that many changes and variations may be made therein, by those skilled in the art, without departing from the spirit of the invention, or exceeding the scope of the appended claims.

What I claim is:

l. A boiler stand comprising a plurality of leg members having radially disposed side arms attached thereto, a leg and side arm constituting a section of the stand, each leg being formed from a single piece of angle iron having a foot member integral therewith, a cut-out portion in the side of the angle member upon which the footis formed, adapted to receive the edge of a boiler, .an aperture in the other side of the angle member, each of said arms being formed from a fiat piece of metal, the piece being slotted and adapted to seat in the aperture in the angle member, the entire arm lying in a plane at right angles to the leg, and a plurality of bolt receiving openings near the end of the arm whereby the sections are adjustably held together.

' 2. A boiler stand comprising a plurality of leg members having radially disposed side arms attached thereto, a leg and side arm constituting a section of the stand, each leg being formed from a single piece of angle iron having an integral foot member formed by turning up a portion of the angle iron, a cut-out portion in one side of the angle member adapted to receive the edge of a boiler, an aperture in the other side of the angle member, each of said arms being formed from a flat piece of metal slotted at one end thereof to form tongue members, one of said tongues being adapted to engage with a side of the angle, the other tongue member being seated in the aperture in the angle member, the entire arm lying in a plane at right angles to the leg, and a plurality of bolt receiving openings near the free end of the arm whereby the sections are adjustably held together.

3. A boiler stand comprising a plurality, of leg members having radially disposed side arms attached thereto, a leg and side arm constituting a section of the stand, each leg beingformed from a single piece of angle iron having a foot member integral therewith, a cut-out portion in the side of the angle member upon which the foot is formed, adapted to receive the edge of a boiler, a recessed portion in said side of the angle member and an aperture in the other side of the angle member, each of said arms being formed from a flat piece of metal cut away at one end thereof to form a projection and a tongue member adapted to seat in the recessed portion and aperture respectively, formed in the sides of the angle member, the entire arm lying in a plane at right angles to the leg and a plurality of bolt receiving openings near the free end of the arm whereby the sections are adjustably held together.
